placed about a singletree may be readily controlled.

A- further object is to produce. a device which is economical to manufacture and one which is readil transportable A further- 0 ject is to provide a-devi'ce which is rigid in construction and therefore one which will not'become easily disarranged.

' Other objects and advantages will be ap parent during the course of the following description. I

In theaccompanyingdrawings forming a part of this specification and in which like numerals are employedtodesignate like parts 0 throughout thesame,

Figure II is across section taken on the line 22 of Figure I, in dotted lines showin the open position'of the device.

It is very importantto water the root areas of a tree several times a year, particularly so in climates where there is very little rainfall at certain seasons. It is then common practise to irri te with the result that'if flood irrigation 1s resorted :to, much more water is used than is necessary. The average small orchard is not e nipped to flood'irrigate, and therefore it has een common to lay a hose adjacent the base of the tree; This does not give proper irrigation forthe reason that the water runs away-faster than it can'reach the root area. I have therefore produced a sprinkler which may be placed entirely around the base of a tree, and by boring holes in the sprinkler at predetermined polnts, a stream of water is caused to radiate in all directions from-the base of the tree so as to give an even distribution.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the ordinary supply pipe which may be a hose or any other supply.

To this is secured a coupling '6 having a nipple 7 to which is secured a T 8.

Figure I is atop plan view of my device, gro

The T '8 carries two diverging semi-annular sprinkler heads "9 and 11, the oppositeends being cappedas shown at 12 and 13, respective y.

The tree is indicated at A. In order to '55 securean evendistribution of the water from the sprinkler heads'9 and 11, I ,provide a plurality-ofjets which may takerany' form,

here shown as iholes bored in the :heads, and

designatedby the numerals lrand 16 and 17. '60

It will'be noted that these holesare placed at difierentangles and consequently the hole 14 will'throw the water in a -circle a given distance about the tree, and the Zholes .16 will throw the water in a circle an -:even distance away from the tree, while the d1d1es17 will throw the water a still .diiferent distance. Holes 18*perm'ita portion of the *water to be directeld .down *into engagement the un The result of this construction that the device maybe readily placed :about :a :tree as shown in Figure I by swinging one .of the sprinkler heads to the dotted line position of FigurelI, after which the head placed about the tree and the upwardly swinging :Eortion is moved back to its normal position.

y now turning on the water so that the-jets throw their spray the desired distance from the tree, it W111 be evident that the ground about the tree will receive a thorough soaking.

It :is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that'variouschanges relative to the shape, 35 size, material and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim In a sprinkler, a pair of substantially semiannular sprinkler heads pivotally connected at their inlet ends with a supply pipe and having their opposite ends closed, said sprinkler heads being adapted to lie in a common plane with each other, and jets formed in said heads so as to cross .a series of concentric sprays.

In testimony whereof I afiix my signature.
